Step-by-Step Red Lentil Soup Recipe
Now that we have the ingredients ready, let’s go through the step-by-step process of making the perfect red lentil soup. This recipe is easy to follow, requires minimal effort, and results in a rich, flavorful, and nutritious dish.
Preparing the Ingredients
Before cooking, take a few minutes to prep your ingredients:
- Rinse the Lentils: Place the red lentils (1 cup) in a fine-mesh strainer and rinse them under cold running water until the water runs clear. This helps remove excess starch and prevents the soup from becoming too thick or gummy.
- Chop the Vegetables: Finely dice 1 onion, 1 carrot, and 1 large tomato (or use canned diced tomatoes – 1 cup). Mince 3 cloves of garlic and, if using, grate 1 teaspoon of fresh ginger.
- Measure the Spices: In a small bowl, combine 1 teaspoon cumin, ½ teaspoon turmeric, ½ teaspoon paprika, salt, and black pepper.
Cooking Process
Now, let’s start cooking!
- Sauté the Aromatics:
- Heat 2 tablespoons of olive oil in a large pot over medium heat.
- Add the chopped onion and sauté for about 2–3 minutes until soft.
- Stir in the garlic (and optional ginger) and cook for another 30 seconds until fragrant.
- Add the carrots and tomatoes and cook for 3–4 minutes, stirring occasionally.
- Add Spices and Lentils:
- Sprinkle the cumin, turmeric, and paprika into the pot, stirring well to coat the vegetables.
- Add the rinsed red lentils (1 cup) and mix everything together.
- Pour in the Liquid:
- Add 4 cups of vegetable broth (or water) and stir.
- Bring the mixture to a gentle boil, then reduce the heat to low and let it simmer for 20–25 minutes, stirring occasionally.
- Blend or Leave Chunky:
- If you prefer a smooth, creamy soup, use an immersion blender to puree the soup directly in the pot.
- If you like a chunky texture, leave it as is or blend just half of the soup for a creamy yet textured consistency.
- Final Touches:
- Squeeze in 1 tablespoon of fresh lemon juice to enhance the flavors.
- Taste and adjust seasoning if needed (add more salt, black pepper, or a pinch of red pepper flakes for spice).
Best Cooking Techniques for Perfect Texture
To ensure your red lentil soup turns out perfect every time, follow these tips:
- Avoid overcooking – Red lentils cook fast! Overcooking may cause them to break down completely, making the soup too thick.
- Adjust the liquid – If the soup is too thick, add more broth or water. If it’s too thin, simmer uncovered for a few extra minutes.
- Use fresh spices – The flavor of your soup depends heavily on your spices, so make sure they are fresh for the best taste.
- Blend carefully – If using a regular blender, let the soup cool slightly before blending in batches to avoid splattering.
With these simple steps, you’ll have a delicious, homemade bowl of red lentil soup ready to enjoy!
